I installed GNU Octave 4.0.0 by compiling from source as explained here. However the GUI does not work - that is, if I click on the Octave Icon, nothing happens. However, when I start Octave from terminal all it's fine, but still no GUI. The same question as been asked here, but the answers don't seem to solve the issue. I have elementary OS 0.3.1 Freya (64-bit).
Any help is much appreciated.
